The Psychic Gem

Garnet. You all know her.
The outcome of a Ruby and Sapphire's love. The head fusion of the Crystal gems.

And the friend of the Psychic Gem.

But Garnet, with her neutral face and mirrored sunglasses, is good at keeping secrets. Very good.
Good enough that the entire time period before Ruby and Sapphire fused is a complete mystery to everyone but herself.

Herself and the Psychic Gem.

There are legends. Of a giant, four armed, winged angel who defeated Jet, White Diamonds strongest and most trusted admiral.

She was known as the Psychic Gem.

Some say the angel is still around, some say she was shattered, but no one really knows where she is or what happened.

So falls the Psychic Gem.

But when Onyx comes back to the Milky Way, futures so unprobable they seemed impossible will become reality. Secrets so carefully hidden will be found. And friendships severed long ago will be restored.
